I've been thinking about buying a Q2. However, I was stopped in my tracks when I read, and I quote, "It's JPEG files are some of the absolute worst I've seen in a modern digital camera." This sentence was taken from Dan Bracaglia, of DPREVIEW, who reviewed the Q2.
I understand your concerns as I shoot RAW+ JPEG and I like the jpeg images to look good too.
The Leica Q2 review by DPREVIEW was done almost 4 years ago. I believe one of the keys that contributed to the less eye pleasing jpeg outputs back then was the strong cool temperature biased AWB, and even worst, it could be somehow inconsistent under mixed or artificial lights.
However, the AWB is now very reliable after the last firmware update ( although Leica didn't mention anything) . AWB will no longer bias to very cool temperature in most situations, if not all. If warmer tone is preferred or you want something else, you can always dial in the temperature or customize it through grey card. I found that the SOOC images are rich and pop. Leica Q2 doesn't have the film sim recipe control like Fujifilm, so it may be less fun or exciting in that regard, but I still found SOOC images excellent.
Tendency of blown highlights was also one of the more common complaints on the internet.
But Leica also addressed that issue through the last firmware update. It introduced Highlight weighted metering.
I personally don't need to use the highlighted weight metering often as long as I pay attention to the blinkies and make the best exposure decision for the scene manually. I found that way yields the optimum SOOC jpeg results. And in the situations of needing to recover dark area in PP, it is usually not a problem and easy.
To further spice up the jpeg outputs, Leica also introduced iDR, and parameter adjustment to jpeg image properties.
iDR is helpful to optimize the dark areas in high contrast scenes for jpeg. I am still experimenting which setting is the best. Auto is pretty much the go-to setting for most people, and for me initially. However, setting it to low or standard will maintain better contrast and saturation of the scene in SOOC jpegs, hence the pictures may pop a little more.
Also adding +1 contrast to Vivid and Standard makes the SOOC jpeg look even better to me.
Of course, you will always get the best out of the files by editing RAW as with all other brands.
My question is this. Why hasn't anyone who bought this camera mentioned the bad color in camera JPEG? Also, talked about the blown highlights, which I can see in the sample photos? These problems are unforgivable in a $5,000 camera, as it is in a $400 point and shoot.
